BOOK-WRAPPER.

Specification of Letters Patent.

Patented May i6, i916.

Application led September 20, 1915. Serial No. 51,728.

To all whom t may concern.

Be it known that I, MorozUMr Okura, a subject of the Japanese Empire, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Book-VVrapper, of which the following is a specification.

My invention relates to improvements 1n a book-wrapper; and the object of my 11nprovement is to provide a book-wrapper which, without losing its simplicity, does not slip from the cover of a book, but which can be removed from said cover instantly, without harming either the cover or the wrapper itself. I attain this object by the device illustrated in the accompanying drawing, in which- Figure l is a top view of the blank from which the book wrapper is formed. Fig. 2 is a blank with its projections folded. Fig. 3 is a top viewof the completed wrapper. F ig.'4; is a perspective view of the coinpleted wrapper.

Similar letters refer to similar parts throughout the four figures.

A indicates the central portion of said wrapper which is the portion to cover the back and sides of a book on the outside; each one of the portions B B is a portion of said wrapper which is to cover the inside of the cover of a book; each one of the portions C C C C is a projection made either at one of the top corners, or at one of the bottom corners, of said wrapper; each one of the lines D D D D D D is the line on which the crease will appear, when said wrapper is folded for use; each one of the wave-like lines E E E E indicates the position where mucilage is applied; and each one of the dotted lines F F F F indicates the position of the projection C, when the portion B is folded.

Uopiea of this patent may be To put the wrapper above described into use, the cover of a book is put upon the portion A of said wrapper, and one of the portions B B is turned over the inside of one half of said cover, and then those two projections C C which are the direct projections of said portion B are inserted between the portion A of said wrapper and said cover; the same thing is done with the other half of said wrapper. Vhen said projections are inserted as above described, both the wrapper and the cover coperate to keep said pro jections in position, and make said wrapper serve the purpose of protecting said cover without slipping.

The mucilage is applied to said projections, because of its being serviceable whenever either the -quality of the cover of a ook or the constant use of a book requires the pasting of said projections to the portion A of the wrapper.

I believe that a book-wrapper which is so simple and at the same time so useful as the book-wrapper above described has the qualities of being a new and useful bookwrapper; therefore I claim:

A book cover protector comprising a rectangular sheet, narrow rectangular portions on two opposite sides of the sheet, each portion being folded inwardly and lying parallel to the sheet, tabs projecting from the opposite otherwise free ends of the narrow portions, said tabs being folded inwardly and lying between the sheet and the narrow portions, and a mucilaginous substance affixed to the face of each tab opposing the sheet.
